Shoot tips from two strawberry (Fragaria anariassa L.) cultivars, Gabi and Edpeerenwere cultured on MS medium supplemented with 0, 0.5, 1.0, 1.5 or 2.0mg /1 of BA tostudy their effects on number, length, fresh weight and dry weight of shoots. Thestudy also included measuring the effect of different concentrations of IBA (0 , 0.1 ,0.3 , 0.5 or 1.0) mg / l on rooting percentage, roots number and length. This studyalso included the acclimatization processes for plantlets in sand and a mixture ofsand and peat moss media. Results indicated that addition of BA to the nutrientmedium led to a significant increase in all investigated traits in comparison with the control with obvious superiority of 2 mg /l which reflected positively on the meannumber of shoots (20.0) shoots / plant, the fresh and dry weight were 1237.73 and136.4 mg respectively, especially with Gabi cultivar, the result showed that all thelevels of IBA in the nutrient medium led to 100% rooting after 6 weeks of plantingof both cultivars compared with 50% of in control. It was also noticed significantincreases in the roots number and shoot lengths when IBA concentration wasincreased in the medium. The best growth for the rooted plantlets was found to be1:1 sand: peat moss which showed survival percentages of 80 and 90% after 4weeksof planting Erdpeern and Gabi cultivars respectively.
